This slim volume is a valuable contribution to our understanding of the historic occurrence of the California Condor from California north of San Francisco Bay to southern Canada. It is perhaps not widely recognized that the condor was at one time a conspicuous element of the Pacific Northwest’s avifauna. We may associate condors with the open, semi-arid mountain ranges of southern California, their last redoubt, rather than with the dense coastal forest habitats to the north. However, the authors compile a carefully scrutinized and apparently exhaustive list of 81 reports from the Pacific Northwest dating from Lewis and Clark’s first observation while they descended the Columbia River gorge on 28 October 1805 to a 1925 report from Siskiyou County, California. Dave DeSante’s sighting of a single condor soaring over the Stanford University campus in March of 1971 falls a bit south of the region covered by this study (J. Nisbet, Visible Bones, Sasquatch Books, Seattle, 2003, pp. 55–58).
